User manual
Remark: JTAG access to the LPC2400 is only possible if no code read protection is
selected, see
The JTAG port may be used either for debug or for boundary scan. The state of the
DBGEN pin determines which function is available. When DBGEN = 0, the JTAG port may
be used for boundary scan. When DBGEN = 1, the JTAG port may be used for debug.
The EmbeddedICE logic contains 16 registers as shown in
ARM7TDMI-S debug architecture is described in detail in "ARM7TDMI-S (rev 4) Technical
Reference Manual" (ARM DDI 0234A) published by ARM Limited.
